Hi ,
Thanks for the advice
I tried first with a CIFS share , checked by accessing it from other
machines . created CIFS share (Left hand side of menu, Data Center,
Storage) ,
Now when I go to the VM , backup option , and click backup I can only see
the local storage, I am not able to see the CIFS share which I created
Similarly I did with NFS server and shared directory , checked it by
accessing it from other hosts. Created NFS share (Left hand side of menu,
Data Center, Storage).
This also when I go the the VM, backup option and click back I can only see
the local storage , not the NFS or the CIFS storage which we created
earlier . The prox mox version is 6.3-3.
But when I give a df-h , I get the results
oot at server-1:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 378G 0 378G 0% /dev
tmpfs 76G 13M 76G 1% /run
/dev/mapper/pve-root 29G 6.2G 22G 23% /
tmpfs 378G 69M 378G 1% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 378G 0 378G 0%
/sys/fs/cgroup
/dev/sdb2 511M 312K 511M 1% /boot/efi
/dev/fuse 30M 72K 30M 1% /etc/pve
*//10.115.129.160/proxmox <http://10.115.129.160/proxmox>
1.0T 359G 666G 36%
/mnt/pve/backup10.115.129.169:/home/itsupport/nfsshare 1017G 14G 955G
2% /mnt/pve/nfsbackup*
tmpfs 76G 0 76G 0% /run/user/0
So from the df -h , we can see the CIFS and NFS, but through the web
interfaces, backup option do not show them in the drop down menu.
I am thinking in this situation, to make use command line and run the
backup so that I can specify the location (cifs or nfs share) to which I
can copy the disk image
I will be posting another thread on requesting on how to use command line
to take backup of VM images
Thanks
